LIFE SAVYING BOAT Filed July 9, 1928 2 Sheets-Sheet 2 Pam? Haifa/2 INVENTOR ATTORNEY Patented Feb 25, 1930 {PATENT OFFICE westerners; or 1 m MISSOURI LIFE-sAvnie BOAT Application filed. July 9, 1928. Serial No. 291,435.

Ehis invention relatesto life saving devices and its general object is to provide an enclosed water-tight life saving boat that is pri- 5 the like and is adapted to be detachably' secured to the deck of a vessel withwater-tight means of-communication between the same and theinterior of the vessel, whereby the 'o'ccupantsof the vessel maypas's therefrom into the-life saving boat which when released from the-vessel, if the latter is submerged will rise to the surface, with the result the boat is extremely useful in" saving the occupants of disabled submerged vessels in an 1 easy and expeditious manner.

I Another object f the invention is to provide'a lifesaving boat for submarine vessels 7 and the'like, that is adapted to be detachably secured to thevessel and: includes means for supporting the boat when secured, and said means also serves as a keelor center board 7 when the boat is floating so as due rolling thereof; 1 j a A further obj ectof the invention is to provide a life. saving "boat ofthecharacter set forth, that iscapable of housing supplies and drinking water, and can be steered whereby it can be directed as desired after being rele ase'difrom'the vessel carrying the same;

A still further object of the invention is to provide a life saving boat for submarine vessels, that is shaped to overcome resistance to a minimum'so' as not to retardt-he speed of a submarine 'whenthe latter is submerged, and the boat will not materiallyfinterfere with eflicient operation of the submarine vessel when attached thereto.-

' 7 Another object of the invention is to provide a life saving boat that is rather simple in 40 construction, inexpensive to manufacture and install, and is eflicient in" operation and service.

fThis invention also consists in'certain other features of construction and in'the combination, and arrangement of the several parts, to be hereinafter fully described,illustrated in the" accompanying drawings and specifically pointed out in the appended claim. Indescribing my invention in detail,'refto prevent unerence' will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which: manly designed for submarine vessels and I Figure 1 is a view illustrating the application of my life saving boat to a submarine vessel and the manner in which the boat rises to the surface when detached from the submarine vessel. I

I Figure 2 is a sectional view taken approximately on line 22-of Figure 1 looking in the. direction of the arrows.

Figure 3 is a longitudinal sectional view taken through the life saving boat per se.

Figure 4 is a fragmentary bottom plan view.

well known type and for distinction is indicated'by the letter A. The submarine vessel has arranged on its deck at appropriate places openings in the nature of manholes and secured to the deck and rising from about the openings are flanged members 1 having upstanding annular flanges as best shown in Figure 2 of the drawings. i

The life saving boat is providedwith an annular flange Q depending centrally of its bottom and being of a size to snugly fit within the annular flanges of the flange members 1, and the life saving boatsare adapted to be secured to the deck of a vessel through the instrumentality of bolt and nut connections 3 extendingv through the bottom of the boat about the annular flanges 2 thereof and threadedly received in inwardly extending projections formed withthe vessel and having threaded bores to accommodate the bolts as shown in Figure 2.

Formed in the bottom of the life saving boat is an opening adapted to be aligned with the openings formed in the vessel when the boat is secured thereto and the opening of the boat is closed byahatch door kwhich is held in operative position by latches 5 as best shown in Figure 4 of the drawings. The door dis provided with a suitable gasket so thata water-proof connection is formed between the door and its opening. By this construction, it will be apparent that the occupants of the vessel may pass therefrom into the life savingboat, when the vessel is submerged. Of course, the door t will be removed as long as the life saving boat is attached to the vessel, but when the occupants of the vessel have passed into the life saving boat, the door is replaced and secured in position by the latches 5.

The life saving boat includes a central compartment which as shown is cylindrical in formation and. provides the quarters for the occupants thereof. The-central compartment is indicated by the reference numeral 6 and disposedupon opposite sides of the opening formed in the bottom thereof are plat forms 7 providing a floor. Arranged in the said compartment 6 are drinking water tanks 8 which have supported thereon food containverslor boxes 9. A pump 10 may also be provided within the central"compartment, as

well as a radio: set or like signallingmeans 11', and formed in the top of the life saving boat, preferably centrally thereofisan: openening providing a manhole, and this opening is square, with aflange 12rising, from about the upperedgesthereof as best shown in Figure 5 of the drawings.

,The flange-12' supports a hatch door 13 which is: secured inclosed position by bolt andnutconnecti'ons 14 arrangedin a manner wherebyythe nuts can be removed from the bolts from the interior of the compartment 6.

The boatis'further provided with portholes 15 arranged at the most appropriate places an'dgthese' portholes may be of'any well known. construction but in anyevent are water-tight when closed.

The boat is formed with air chambers 16 extendingfrom the oppositeends of the cen tralicompartments 6 and these air chambers are conical in form. as best shown in Figure Each of the chambers are provided with valved; openings formed in the partitions 17 which provide the central compartment and these'valve openings are designed for filling the chambers with. air or'removing some of the .air therefrom" if desired.

A rudder 18: isprovided for the boat and i .includes a shank l9extending into one-of the air chambers 16. The shank 19 is mountedififor rotation. in: abearing 20 and has securedxto its upperend a gear segment; 21

which is disposed. in mesh with a gear 22 secured to one end of a shaft 23 having. secured tov its opposite end a. hand wheel 24. disposed Within the central compartment as shown.

While the lifesaving boat may be made in various sizesinthe event it-is madein a relative large-size, Iprovide' ailadder 25 extend- .bedetachably secured to vessels of all types and can be readily removed therefrom when desired. WVhen it is' necessary or desired to use a life saving boat, persons can freely pass therein through the medium of the opening formed in the bottom thereof, and when the required number of persons are in the life boat the latch door 4. is secured into: place, then'the boat. is released: from its-vessel by removing the bolts of the bolt and nut con nections 3 from their threaded bores. Should the vessel carrying the life. saving boat be submerged, when the boat is released there.- from, it will rise to the surface due to. the buoyancy suppliedby the air intheairchambers 16,with the result that the boat can readily save the:li-ves of the occupants offa disabled submerged vesselin an easy and-expeditious manner.

boat, it will set upavery little resistance when secured to a submarine ves'sel and therefore are spaced vparallel!longitudinally disposed strips 26 having inclined flanges-2% formed therewith for the; purpose of securing-the strips to the boat, and these strips not; only act as appropriate supporting means for the boat when the latter is'secured to a vesse'l as shown inFig ure 2-,. but serve as .keelsto' pre- Due to thenovel shape of 'theqlife saving 7 vent undue rolling of :the boat when thel-atter is floating.

It is thought from the foregoing description that the; advantages. and. novel features of my invention: will be readily apparent."

I desire it tobe understood that'I may make changes in the construction and inrth'e combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is: I r

A life saving boat comprising a cylindrical compartment, air chambers formed with the ends thereof, partitions; dividingthe. compartments from the'chambers and arranged atthe juncture of the compartments with said chambers, said partitions having valved openings, means for closing inlet and outlet:

manholes formed in the top and bottomof said compartment and; in alignment Iwithv each other,means for securing saidv boatto I a vessel and being operable from the. interior of said compartment,steering-meansfor said} boat, longitudinally disposed strips depending centrally and vertically from said bot-- tom upon opposite sides of the inlet manhole, and flanges formed With the upper edges of said strips and being secured to the bottom;

In testimony whereof I aflix my signature.
